I found a deal that I couldn't pass up on a Glock 21. It was a range gun that they were selling off. It needed a new trigger spring, and while they were at it Glock service replaced all the internals including the trigger mechanism, striker, recoil spring -- even the sights! So it was basically a brand new gun. At least the rounds are interchangeable with my Colt 1911!! And 13 rounds of .45 ACP feels good in my hands!
